We know there's little love between the pair and this evening sees their clashes continue.
As the bootcamp moves on to Simon Cowell and his Overs, Raign is back stage and ready to sing.
Cheryl snipes, while punching her fist into her other hand: "Oh my God, look at what is coming next.
"I am not in the mood in tonight."
Raign - who claims she "nailed" her previous performance - tells cameras: "All my passion, all my desperation to be on that seat, I hope I can portray that just in my performance."
Her performance of Wicked Game by Chris Isaak gets a standing ovation but Cheryl is not impressed, at first refusing to comment and passing the microphone to Mel.
The Spice Girl says: "I found it all a bit strange."
Raign replies: "It's okay to be a bit strange sometimes, I'm here to represent the misfits."
Cheryl then does comment: "It doesn't do anything for me."
Simon adds: "You are what I call marmite, you either love you or hate you, you have a great singing voice."
"I love her!" gushes Louis Walsh.
Raign then bitches: "I'd love nothing more than be mentored by people whose opinion I really respect."
Cheryl whispers: "I am literally allergic to her."
The X Factor 2014 airs tonight at 8PM on ITV.
